2 Naming and test methods
GB 292182
The commercial names of gas chromatography stationary liquids are mainly scientific names. For the sake of simplicity, intuitiveness and consideration of customary names, some should be distinguished from scientific names. The naming of these stationary liquids is stipulated as follows: 2.1 Polysiloxane stationary liquids are called "silicone oil", "silicone elastomer" and "silicone grease" according to their apparent states. For unsubstituted polydimethylsiloxane, it is called "methyl silicone oil" or "methyl silicone elastomer". The molecular weight is taken as the grade and placed after the name.
For substituted polydimethylsiloxane, the percentage of the group content of the substituent is taken as the grade and placed after the name, such as: "Vinyl Methyl Silicone Elastomer-01" (containing 1% vinyl); "Phenyl Methyl Silicone Oil-50" (containing 50% phenyl), "Diphenyl Methyl Silicone Elastomer ~10" (containing 10% phenyl). The "two" in the diphenyl in the above example indicates the structure of two phenyl groups connected to one silicon atom. For polydimethylsiloxane with two or more substituents, the names and contents of the characteristic groups are arranged in order of polarity, such as: "Cyanoethyl Phenyl Methyl Silicone Oil-25/15" (containing 25% cyanoethyl and 15% phenyl). 2.2 For the names of ester-type stationary phases, the acid is always placed in front, for example: dioctyl phthalate. 2.3 Polyester-type stationary phases are uniformly named according to the following principles based on the molecular structure. 2.8.1RCOOfG3nH is called mono-acid poly-acid glycol ester. For example, CnH23COO(CH,CH,O)nH is called "mono-dodecanoic acid polyethylene glycol (400) ester".
2.8.2 OOCRCOG3n is called poly(ethylene glycol) ester of a certain diacid. For example: EOOC(CH2)COOCH,CH2n is called "polyethylene glycol adipate".
2.8.3R·COOEG3nOCR is called poly(ethylene glycol) ester of a certain diacid. For example: C17H35COO(CH,CH2O)nOC17H35 is called "polyethylene glycol dioctadecanoate".
Note: -G- represents -(CH2)mO-, m=2 or 3.2.4 The names of normal alkane stationary phases can omit the words "normal" and "carbon". For example: n-hexatriacontane is called trihexatriacontane. 2.5 Any straight-chain hydrocarbon or hydrocarbon group containing a methyl group at any position on the chain, its isomers or isomer mixtures are called isoalkane or Isoalkyl CH3
(expressed as iso- in English). Isomers that do not belong to this chain structure are named using the domestic system. For example: CH3·CH·CH2CH2·CH2·CH2·CH2 is called isooctyl, and the stationary liquid containing this isomer or isomer mixture is diisooctyl phthalate. And CH3·CH2·CH2·CH2·CH·CH2 should be named according to the system, called 2-ethylhexyl, and the stationary liquid containing this structure is di(2-ethyl)hexyl phthalate. 2.6 Hydrocarbons, alcohols, mono- and dicarboxylic acids, those with less than ten carbon atoms are represented by heavenly stems (i.e., A, B, C, D), and those with more than ten carbon atoms are represented by heavenly stems (i.e., A, B, C, D). 1, 12, 13 are used to represent them. Lauric acid, palmitic acid, and stearic acid are used as aliases for dodecanoic acid, hexadecanoic acid, and octadecanoic acid.
2.7 The substituents and functional group positions of gas chromatography stationary phases are represented by digital numbers. For example: original name
α-nitronaphthalene
β,β°-oxydipropionitrile
current name
1-nitronaphthalene
2,2'-oxydipropionitrile
2.8 When there is only one structural formula for a commercial stationary phase, the overly long substituent position number can be deleted, or the scientific name can be shortened according to custom. For example:
a. 1,2,3,4,5,6-hexa(2-cyanoethoxy)hexane is called "hexa(2-cyanoethoxy) "Hexane"; N, N, N', N'-tetrahydroxyethylethylenediamine is called "tetrahydroxyethylethylenediamine", 1,3,3,5-tetramethyl-1,1,5,5-tetraphenyltrisiloxane fixing liquid is called "diphenylmethyltrisiloxane-50" (containing 50% phenyl).
GB2921-82
b. Bis-(p-hexylbenzoic acid)-o-methylhydroquinone ester is called "liquid crystal MPBHxB", 2,6,10,15,19,23-hexamethyltetracosane is called squalane.
2.9 For domestic fixing liquids with longer Chinese names and clear molecular structures, if there are similar products abroad, the commonly used product transliteration names abroad (see Appendix B) shall be used, for example: Span, Tween. For domestic stationary fluids with long Chinese names and clear molecular structures, but which have registered trademarks abroad, or for domestic stationary fluids whose molecular structures are unclear or are not composed of a single compound, they cannot use the transliterated names of similar foreign products, but must customize simple and easy-to-remember product names. For domestic stationary fluids that need to customize product names, the product labels should indicate the foreign brand names that are similar to it, for example: High Temperature Grease I (similar to Apicone L).
2.10 For chromatographic stationary fluids imported from abroad for repackaging, the Chinese and English names on the labels should use the domestic unified names. The foreign names can be annotated with the original packaging name or code, and the words "imported repackaging" can be indicated, for example: "Phenyl methyl silicone oil-25" Phenyl methyl silicone oil-25 (DC550) (imported repackaging) For foreign imported repackaging chromatographic stationary fluids that do not have a unified name in China, the Chinese name can be directly transliterated, and the foreign name uses the original name. 2.11 When translating the foreign names of fixatives, the names should be translated according to their molecular structures and should not be translated literally. For example, Propylene carbonate should not be translated literally as propylene carbonate, but should be called propylene carbonate (1,2) ester according to its molecular structure. For another example, fixatives containing polyethylene glycol structures in their molecules are collectively referred to as polyethylene glycols regardless of their foreign names. For example, Polyoxyet hyleneglycoi 400 should not be translated literally as polyoxyethylene glycol (400), but should be called polyethylene glycol (400). 3 Naming procedures
Units that develop new fixative products should name them according to the provisions of this standard and report them to the professional standardization technical centralized unit. The report should be accompanied by an appraisal report and conclusion. After approval by the centralized unit, it shall be reported to the Ministry of Chemical Industry for filing. 117
